Climate change and the ecology and evolution of Arctic vertebrates.

2012

25 pages; International audience; Climate change is taking place more rapidly and severely in the Arctic than anywhere on the globe, exposing Arctic vertebrates to a host of impacts. Changes in the cryosphere dominate the physical changes that already affect these animals, but increasing air temperatures, changes in precipitation, and ocean acidification will also affect Arctic ecosystems in the future. Adaptation via natural selection is problematic in such a rapidly changing environment. Adjustment via phenotypic plasticity is therefore likely to dominate Arctic vertebrate responses in the short term, and many such adjustments have already been documented. Changes in phenology and range w…

Riella cossoniana Trab. (Riellaceae, Marchantiophyta) new to France

2014

Riella (Riellaceae, Sphaerocarpales) is a genus of aquatic liverworts with disjunct range in areas of Mediterranean-type climates. Riella has been traditionally subdivided into two subgenera, subgenus Riella, whose plants show smooth or papillose female involucres and Trabutiella, whose plants show winged female involucres. To date only three species of Riella are known in France, all belonging to subgenus Riella. During the course of a study of the plant diversity of temporary brackish ponds in the Camargue area (Southern France), soil sediments were collected from 10 localities and cultivated in the laboratory. From cultures of five of these localities emerged dioicous plants of Riella sh…

Riella bialata Trab. (Riellaceae, Marchantiophyta): A new addition to the European liverwort flora

2013

[EN] Riella (Riellaceae, Sphaerocarpales) is a genus of aquatic liverworts with a disjunct worldwide distribution in areas of seasonal Mediterranean-type climates. Its centre of diversity is located in the Mediterranean basin, where about half the species number of the genus is concentrated. In the course of a worldwide revision of the genus Riella, plants from a monoicous species with wingless, not papillose and smooth involucres were found in two distant Iberian localities. These plants showed a geminate dorsal wing, unlike the single wing occurring in the remaining species of the genus. This character unambiguously assigns these populations to R. bialata, a species known to date from a s…

The security of mobile business applications based on mCRM

2020

A development of mobile technologies, and their common use in business, creates new challenges for people dealing with data security in the organization. This paper explores the types and nature of threats to the enterprise that result from the widespread use of business applications on smartphones (e.g. mobile CRM). The analysis has been focused on smartphones and tablets running on the Android operating system. We used STRIDE - a threat modeling technique commonly used to detect vulnerabilities in software security. We propose its modification to better design and implement solutions for the security of mobile devices. We also used the Data Flow Diagram and the Attack Tree concept to anal…

Typification of the name Statice calcarae (Plumbaginaceae), basionym of the threatened endemic Limonium calcarae

2018

Limonium calcarae (basionym Statice calcarae), a rare diploid species endemic to Sicily, is one of the few members of the genus that occurs in the inland areas of the island. According to IUCN criteria, it has been assessed as critically endangered but recent data on its distribution, demography and threats affecting its populations are lacking. A lectotype is designated, preserved at PAL, and isolectotypes have been traced and verified in other European herbaria.

Can grassland plant communities be preserved on road and railway verges?

2000

Semi-natural grasslands are a threatened biotope type in many countries. Typical grassland plant species are adapted to continuous grazing or mowing that keeps the envi- ronment open. With the decline in grassland area, these spe- cies are ever more reliant on alternative habitats such as road verges. To find out whether plant communities comparable to those of semi-natural grasslands can be maintained on modern road and railway sides, the vegetation of 92 grasslands and 90 road and railway verges was studied. These biotope types were compared with each other according to their community structure, total number of species, number of grassland species and restricted-range diversity. Further …

Home range and excursive post-breeding movements of Eurasian Eagle-owls revealed by GPS satellite transmitters

2021

Investigating space use of wild birds provides important knowledge of bird behavior and ecology, which is crucial in the management and conservation of threatened species. In the present study, we used GPS satellite telemetry to investigate space use and movements of seven adult Eurasian Eagle-Owls (Bubo bubo) in Norway during breeding and post-breeding seasons. Breeding adults had a mean home range size of 42.9 km2 (SD ± 35.1 km2; 95% kernel density estimation Had hoc), and five individuals performed long (>20 km) excursive movements away from their breeding territories during autumn. Such wide-ranging behavior has not previously been reported for adults of the nominate subspecies B. b. bu…

Distribution, ecology, vegetation and conservation survey on the relictual population ofCarex panormitanaGuss. (Cyperaceae) in Sicily (Italy)

2013

We report the results of research on the Carex panormitana Guss. (Cyperaceae) population in Sicily, carried out within its locus classicus at the Oreto River (Palermo). The survey led to a morphological, biological and autoecological characterization, to the definition of the current distribution in the site, to an estimate of the number of individuals and to an analysis of its conservation status. The risk status was also assessed and the species was ascribed to the category Critically Endangered (CR), in accordance with the CR B1ab (ii, iii, v) and EN C1 IUCN criteria. Moreover, the phytosociological survey carried out on the meso-hygrophilous vegetation in which the species is dominant a…

Threats and attitudes toward Russian-speaking immigrants: a comparative study between younger and older Finns

2014

Using integrated threat theory as a theoretical lens to detect negative attitudes toward minority groups, this study compares and contrasts the perceptions and attitudes of older and younger Finns toward Russian-speaking minorities in Finland. A sample of high school students between 16 and 20 years of age represented the younger generation, while individuals over 65 years of age represented the older generation. The total sample was 242. Results indicated that there is a positive correlation between threat perception and prejudice. Results revealed that both groups have prejudices against Russian speakers and that these prejudices are related to the perception of realistic threat and negat…
